Old Aikido is Daito ryu
In Daito-ryu, Ueshiba Sensei is respected as one of Sokaku Takeda's best students. And of course, the foundation of aikido is Daito-ryu. During the life of Morihei Ueshiba, aikido was different. This can be seen in the first Aikido masters, students of Ueshiba.
I consider Aikido one of the Daito-ryu styles, in which Oomoto's philosophy appeared. And the real Aikido is as beautiful and effective as Daito-ryu.
